I should correct myself it is not USD 52 but USD 71 , JL tax (by phone) and CX tax (613 HKD) (on website).
But I noted on CX site that says HKD 613 is tax/surcharge and it include all fuel surcharge and taxes and son on.
Well I will wait and see if anybody else know about ZM cause all these taxes are not much and i don't know how they calculate ZM fares.
thanks
